About Unit & FX Calculator MCP Server
LLMs notoriously struggle with complex compound conversions (e.g. converting km/h to mph with specific decimal rounding). Worse, they hallucinate foreign exchange (FX) rates based on their historical training data rather than current markets. This MCP bridges that gap.
Pydantic AI validates every Unit & FX Calculator tool response against typed schemas, catching data inconsistencies at build time. Connect 3 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.
The Superpowers
- Physical Determinism: Converts length, mass, volume, temperature, and speed using the exact mathematical engine of
mathjs. Completely eliminates metric/imperial hallucination. - Live FX Rates: Uses the Frankfurter API to fetch the latest European Central Bank reference rates for absolutely precise currency conversion.
- In-Memory Edge Cache: FX rates are cached in a native V8
Mapfor 1 hour, meaning massive batch conversions run instantly without getting rate-limited.
The Unit & FX Calculator MCP Server exposes 3 tools through the Vinkius. Connect it to Pydantic AI in under two minutes — credentials fully managed, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
